SECURNG MEANS FOR SPLIT TIREJOLDING RMS.

Application filed April 9, 1914.

To all whom. if may concern.' Be it known that l, Joux Knnsnv, a. eltizen of the United States, and resident of Detroit, in the county of `Wayne and State of Michigan, have invented certain new and useful Improvements in Securing Means for Split Tire-Inleidinga Rims; of which I hereby declare the following to be a full, clear, land exact description, such as lwill enable others skilled in the art to which it appertains to make and use the same.

The objects of the invention are to provide a split tire holding rim and means for detachably securing the same to the felly band of an automobile wheel in such a man ner as to prevent circumferential displacement of the. extremities of the rim relatively to each other and to the felly band.

Further objects of the invention are to provide an improved form of construction of the felly band permitting the application interchangeably thereto of rims having Standard clencher flanges Iand of rims having straight side flanges, and adapted to secure straight sided tires having a 10i/n over capacity, that is7 it is adapted to use with the rim for a straight Sided tire having a wider base than that of the standard size without alteration of the felly rim.

The invention comprises a. split rim having inclined over-lapping extremities and interlocking devices for the rim and felly band and for the overlapping extremities of the rim and also the peculiar conformation of the felly band to adapt itI to interclnnigeablo use, as hereinafter further described, shown in the accompanying drawings, and specilically pointed out in 'the claims.

ln the accom )anvmO' drawings Figure l .f l l h is a plan view of the completed joint form'cd A between the extremities of the rim showing straight side langes; Fig. 2 is a longitudinal central section thereof and of the. folly band; Fig. 3 a transverse section of the rim and felly band at y/--j/ Fig. 2, showing one exstraight side flanges; Fig. 4 is a transverse section of the folly band showing one extremity of the rim and recess therein and showing elencher flanges; Fig. is a transverse section of the felly band shown- 'r t clencher rim mounted thereon, and showing the posit-ibn of a straight side rim in 'dotted lines; Fig. G shows a. transverse section of the folly band showing the elevations therein;

Specification of Letters Patent.

Fig. A7 is a transverse section of theV rim and felly hand and clan'iped;-

Fig. 8 isa face view of the clamp;

Fig. 9 is a view of Vthe inner side of the clamp.

1n these views A is the rim, l the felly band. The. rim is diagonally cut to forni inclined overlapping surfaces L and a.

Before making the divisional eut a rigid plate or member. C is attached to the underside of the rim by rivets c, o, or may be made. integral with the rim if desired by depressing the same, and afterward the, diagonal Cut is made extending through the rim and its side flanges and through the member (l.

The plate is provided with slightly extending lower extremities c', c', and pro- .iecting integrally from the substance of the felly band ar."l corresponding elevations 0.1;, the opposed outer edges of which are extended so as to be capable. of entering be.- tween the extended edges of the plate (l in 'the manner of dovetfails and of interlocking therewith when the ends of the. rim are brought. together and moved laterally into place upon the felly hand. The engaging edges of the. plate (l and elevations l1 are preferably reversely inclinedso as to form the doveta] gripping means aforesaid which. eli'ectually prevents circlunferential movement ol' the/rim upon the felly band.

Before the. diagonal cut is made, through the rim A and place (l a rivet hole lt is made, in the rim and plate. the. diagonal eut is then made through the rim and platel and the parts are. rigidly hcld together while a larger countersunk opening r is made? in the. rim from above. which extends to the line. of the. divisional cut., and overlappingboth portions of the rim.

A smaller countersink is made. in the member (`l on the underside at 1" in the inner cnd of the rivet hole.

A rivet 'l of corrcspomling shape to the opening is then put in place and when the, wdremities of the rim are brought together the larger head l5 of the rivet will enter the largo eountersink one portion extending also into the depression X. 'lhe rivet. l is provided with an annular shoulder '1" which rests upon a shoulder T2 at the hot-tom of the 'large cou'ntersink. The head of the rivet, is smooth and extends preferably a trifle above the. surface of the rim.

l.ln this position the rim is moved into ll (l ing outward by the dovelail construction `ot the interlocking plate and elevations upon the telly band. The plate (l also serves to act as a (.lriving plate tor the rim. 4

Openings O, in the rim at the overlapping joint permit the insertion et a tool to relax the tire.

rlhe clenc-lier and straight side rims are as stated interchangeably placed upon the same telly band. Provision ot' this adjustment is made by giving a definite separate seat. tor each type ot rim upon the telly band. l

In Figs. (3 and 7 a. rim provided with straight. side flanges R, R. is shown and one curved annular edge E engages the annular recess E upon the flange F otl the band. These recesses are spaced apart to receive a tire having a wider base than the standard size, suitable to support a straight sided tire havinet 10"(- 0'renter ca )acitv than D h .f

the standard size.

A second annular recess G upon tlange l" ot the telly band receives curved edge ot the standard clenclier the the rim at (t.

Both rims tit intei'changeably upon the band at an equal distance theretrom. (llampsI ll. spaced at equal distances about the rim secure the selected rim iii'place.

The clamps can be used interchangeably to secure either rim upon the telly band and each clamp is'provided with two recesses correspomlin` ,o the recesses E and Gl viz.. I and J upon the rim engaging side, one ot' 40 which I as shown in Figs. 5 and 7 receives the edge otthe elem-her rim and Vthe other J receives the edge ot' the straight side rim. The clamps are also supplied with inclined extensions H which project between the riin 'and telly band and spaces the assembled parts. i l i These engaging or inclined extensions project over Athe telly band to give a broad bearing thereon and increased strength to the assembled parts and the metal is drawn up at the sides at l), I. to add to the strength ot the clamp without increasing its weight.`

Each clamp is also provided with a heel K which engages the inwardly turned flange K of the telly band and upon this heel the clamps find a tiilcrum when the .nuts are tightened upon the bolts.

Bolts L, li pass through the flange hi" and telly L and are provided with nuts M which serve-to tighten the assembled parts. The exact construction ot the clamps and nuts is described in a tormer application.

The inflated tire when put in place holds the ends ot the ring tightly together.y which makes the assembly easy and when the clamps and wedges which are spaced evenly around the rim are tightened, the rim will tit perfectly upon the telly band and the joints will be incapable ot ilvorking upon each other.

ln Figs. and l' the preferred shape ot the telly band is shown to give 'a wide seat to the straight side. riiii and the standard seat to the clenche-r rim.

In li`ig. T the sectional view of the clamp Il shows the same betere the bolt is pnt in place. and nut attached and shows a light and rigid torm ot construction.

llaving described the invention what I claim as new and desire to secure by Letters .Patentis:

1. The combination with a transversely7 split rim and telly band` ot plates secured.

to the riin on opposite sides of the split therein having beveled or dove-tailed edges parallel transversely ot the rim and contacting beveled or dove-tailed lugs upon the telly baml tor engaging said plates.

2. The combination with a transversely split rim and a telly band having a flange, ot members secured to the. inner side ot the rim upon opposite sides of the split therein. said members having a common rim end interlocking member tor alining the adjacent ends ot the rim and the outer edges ot said members being beveled or Adove-tailed and means upon said telly band oppositely beveled or dove-tailed tor engaging the beveled or dove-tailed edges ot said nienibers, the engaging surfaces ot said beveled or dovetailed edges being parallel toeach other transversely oit the rim.

3. rlhe combination with a transversely split rim and a. telly band provided with a flange forming a seat tor one edge ot said rim, ot radially interlocking bearings on said telly band and riin on opposite sides ot the. split in the latter, said bearings being transversely parallel to permit the tree movement ot the rim across the 4telly to find its true bearing upon the seat upon the telly.

band flange. v

ln testimony whereof l hereuntoset my .hand this 9th day ot March. 1914i.
